少壮不努力，老大徒伤悲，请你谈谈对此的想法并如何行动。
Almost everyone knows the famous Chinese saying：A young idler，an old beggar. Throughout history，we have seen many cases in which this saying has again and again proved to be true.
It goes without saying that the youth is the best time of life，during which ones mental and physical states are at their peaks. It takes relatively less time and pains to learn or accept new things in a world full of changes and rapid developments. In addition，one is less likely to be under great pressure from career，family and health problems when young. Therefore，a fresh mind plus enormous energy will ensure success in different aspects of life.
Of course，we all know：no pains，no gains. If we dont make every effort to make good use of the advantages youth brings us，it is impossible to achieve any goals. As students，we should now try our best to learn all the subjects well so that we can be well prepared for the challenges that we will face in the future.
